Thank you for sharing this--extremely helpful

Thank you!

Thank you for the tip!

Just what I needed , great f@@ken tip

Unless you know what you're doing and can identify tappets on a base circle... if you can't, maybe it's not a job for you.

If Harley did what they are suppose to do they would not be where they are today!!

Not really he said the cam bearing looked good. You should always replace the cam bearing with a new cam...

Glad it was helpful!

Glad it helped!

😆 that is a good lesson to learn! Glad you learned it here and not in the shop.

I love S&S, as the push rod adjustment they are confused!! all their push rods are 32 tpi this means to compress the lifter 0.100 thousands you need to turn the push rod 3TURNS +2FLATS to get .100 thou 4 turns gives 0.125 all lifters need to be collapsed 0.100 THOU after 0 LASH .EXCEPT solid lifters wich are used in rare racing applications ,I called S&S tech today and they said 4 turns is old instructions and 3 turns + 2flats IS CORRECT.!!!!!! ,4 Turns is not allowing the lifter to function as it was designed to HARLEY FUELING ETC ALL NEED 0.100

Thank you!

This bike got our Chain Drive 475 cam.

@@SSCycleInc your instructions for a new m8 says 4 turn on push rods for adjustment, some video say 3.5 turn please confirm, I’m doing your kit 475c on a 2021 m8 thanks

Thank you! Glad you're loving the T111!

On a scale of 1 to 10 how hard was the job to do ? Watching the video it looks fairly easy

A 3. Just take your time.

It flows excellent!

@@SSCycleInc Per some calculations, I believe the 114 with the 55mm throttle body wants 285cfm of flow. What cfm is the tear drop rated at?

@@TheHighestGodisGood Almost double your calculation.

@@SSCycleInc I see that K&N says their cfm rating can be found by taking the surface area times 6.03. So, a 2" tall x 6" diameter filter would have: 2" x 6pi x 6.03 = 227.3 cfm. That's why I was worried. And then you have the cover over it, further restricting it (imo). I guess I don't know how a covered filter that small can flow around 570cfm. Is there any website or video that you can point me to, to verify that, or to correct my math on? I'm an engineer and so when the math doesn't add up, I get skeptical. I really want the S&S teardrop (love the look and love that it would go with my S&S 475C cam chest kit I'm getting), so that's why I'm asking. For example, as a gut check to my math, K&N claims their extreme round air filter flows 350cfm, when left uncovered. To me, that makes sense with the math saying a regular round K&N flows about 230cfm. Maybe you are using a different, superior filter and not K&N and that where the difference is? Anyways, I appreciate any help!

@@TheHighestGodisGood Can't really speak to K&N number nor verify their claims. We use a Superflow bench to test all of our air cleaners and we can share that there is only a 10 CFM difference between the mini and an open Stealth air cleaner. The mini cover allows for substantial air flow through the sides and back and flows far more than most engines will use

I've been told by a HD tech friend of mine that the TC sprocket locker fits the M8. I have not tried it though. If it does, let me know please.

I thought the same thing.

Nope, it should've been on the opposite side of that tappet(exhaust), or on the bolt side of the inner(intake) tappet. This way, he almost made sure that the tappet will touch the cuff as soon as he torques it to spec and it rotates a hair. But of course he's the pro, and I could be wrong! LOL

Hey Ed, there shouldn't be any pressure on your cam at this point, so you can simply turn it to the upright position and proceed with your install.

The FXR Style fairing from RWD throws off the traditional Road King look for sure! This job isn't for everyone, we'd be happy to recommend a shop in your area if you'd like?

465 Would be the move for low to mid RPM torque. www.sscycle.com/tech-info/cam-specs-overview We'd recommend the S&S Sidewinder 2:1 www.sscycle.com/products/sidewinder-2-1-for-m8-touring-modelsblack/

We recommend reaching out to our tech team directly on this one. They will be able to walk through the potential problems and get it sorted out for you. Drop them an email at SSTech@sscycle.com or give them a call at +1 608-627-1958.

When changing the cam you do have to have the bike retuned.

Working on one now, should release later in the summer

For this set up, we used the entire cam chest upgrade kit, which is part number 310-1012B. The 475c cam, which is a chain drive cam, on its own is part number: 330-0641 If you are going gear driven on your set up you will want the Pinion Gear part number: 330-0622

If you are swapping over to a Gear Drive cam, you definitely need to check the runout, if you are sticking with the chain drive it is not necessary.

@@SSCycleInc Had two questions, this was the big one, the other was what is the criteria for deciding between chain or gear drive?

Hey @@jjones6173,​ honestly the runout is going to be your biggest criteria. If your runout is not within tolerance you either don't have the choice to run the gear drive, or you have to take your bottom end apart, have it reworked by someone like Darkhorse, and then reassemble to run the gear cams. Or of course you can just run the chain cams. When it comes to decision making, other criteria (assuming you are withing spec) is if you would rather have a slightly louder cam (more engine noise) that transfers power slightly more quickly, or if you would rather have a slightly more quiet cam that requires checking at regular maintenance intervals.

@@SSCycleInc I very much appreciate the explanation

If your bike is currently using it, we definitely recommend you reinstall it (the existing seal can be reused with S&S pump)

No gasket on stock oil pump, so I won't be installing one with my S&S pump. Thanks for the reply.

The correct adjustment for our Quickiee Pushrods is 24 flats or 4 full rotations.

Thank you that was fast great job and great product

@@capecodbiker9902 Happy to help man!

Hey Samir, we don't offer a tuner but you absolutely need to have your bike tuned after upgrading your cam.

Absolutely. www.sscycle.com/feature/valve-train/cam-chest-kits-for-m8

Your 2020 should have had an o-ring on the pump you pulled out. We do recommend running the o-ring to prevent any potential sealing problems.

@@SSCycleInc can it be reused or need to purchase new one?

It’s always safer to purchase a new one. Your local HD dealer should have, or be able to order you one.

@@MrTheDays1 i reused mine, tho the bike had less than 1000 miles on it

It is always a good idea to change the oil out and start off the lifespan of your new cam chest with fresh oil.

You '18 was made before the gasket was added to the original equipment. It's not a bad idea to go to your local dealer and pick one up when upgrading your oil pump to ours.

In order to get the most performance out of your new cam, you will want to retune.

That gasket is not included in the kit, as it is an HD proprietary piece. Your local HD dealer can get you set up with one for a few bucks.

At 24:04? That is a t-handle allen wrench with a ball-head, it allows you to install the bolts with the wrench at an angle without deforming the bolt head, very handy to keep a set around the shop!

Thank you!

@J T J I already tried contacting S&S, Edelbrock, Woods, Black Widow, and a few others. I couldn't get anyone to make it. I guess they prefer to make cams that only halfway fix the problem. You're stuck choosing between total gear cams that can't tolerate runout or having 2 chains so one cam shoe is trapped behind the cam plate.

Yea. But why would you not replace the cam it’s just a couple hundred dollars more and you get a much better cam… more torque and better sound

This is our 475 cam, which is intended as a bolt-in HP cam and pushes the M8s to over 100HP without headwork. As for our oil pump, they offer a 20% flow increase on supply side and 52% flow increase on scavenge.

With a chain cam, it is not necessary to check the runout. With a gear cam, it is necessary to check for runout. You would base the runout tool off of the pinion shaft.

@@SSCycleInc From the S&S instructions for installing the cam support plate: S&S recommends no more than 0.005” of total indicated runout on the pinion shaft while checked in the cases.

@@SSCycleInc I was under the impression you had to check for runout for the oil pump and camplate because this stuff is made out of 7075 Aluninium billet which does not compress and wears and cracks if the run-out on the pinion shaft is too much.

@@FranBunnyFFXII Not sure what you're asking here. Runout spec we share is specific to the gear drive cams. The gears require a tight mesh and crank runout could cause interference. The material used for pump and plate would not be relevant to the runout spec.

@@SSCycleInc Moonshine Harley makes a big deal about checking the runout saying you will damage the cam plate in their KZfaq video. They go as far as to say if it's over 5 thousandths, you can't install the cam chest kit, but they never mention that only applies to the gear drive kit, but that makes sense to me. I really want to do this install myself so is it safe to say if I go with the chain drive kit I don't need to worry about buying a runout checking tool at all?

We've found the best method to be getting the rear tire off the lift and spinning it by hand. Our friends over at J&P have a great breakdown on it.

We recommend soaking the tappets in the same oil that you will be running in your engine.

Hold throttle wide open when cranking over engine usually works for me. It won't start wide open..

@@joshv1440 alrighty perfect just like new pickups. I was told They do it for people in flood areas so you can push water out of cylinders before firing

Prices can vary from city to city and state to state, that is a question best suited for your local S&S Dealer. You you do not currently have one, you can find your nearest dealer here: www.sscycle.com/dealer-center/dealer-locator

@@SSCycleInc what would your company charge?

@@BlownC52000 We manufacture and sell the parts, but do not have a public shop.

Stock inner bearings were fine on this one. Bike is relatively low miles.

@@SSCycleInc Does S&S replacement bearing have cages for rollers? The upgraded bearing has more rollers for better response. You're in there, change it- you have a new one at your elbow.

Replace. Twice as many rollers! I purchased the bearing puller. No brainer.

@@SSCycleIncHD stock cam bearing is an inferior product. With all do respect no competent engine builder would install a new cam in a bearing that has some use on it regardless how little hours are on the engine. Especially the stock HD bearing.

Substantially improved oil flow, improved cooling, cam change increases both horsepower and torque across the RPM range.

@@SSCycleInc Thanks for replying. Another 2 questions please: What is the advantage to gear driven vs chain driven and is there any issue with putting this cam chest kit and cam on a Ultra Classic with 25K miles, as I want longevity for the motor.

@@Old-n-slo-locked-n-leaned Gear drive cam allows for elimination of the wearable chain tensioner as well as more accurate cam timing. Crank run out is the only challenge for gear drive cams, as the gear is designed for a very tight tolerance and any run out on the crankshaft would cause interference. We would recommend the 465 or 476 cam on the M8 Ultra depending on the type of riding you are doing. 465 is more focused on torque and power down low in the RPM range and 475 will produce 100Hp, but does it much higher in the RPM range.

Not a bad plan at all!

Our chain drive kits come with our upgraded tensioners.

Stock is boring!

HD= half done!
